There was a time when a train could bring a whole town together. Some Schwenksville residents may still remember Touch of Dutch Day. The celebration featured the Reading Railroad’s Iron Horse Ramble, which brought a giant steam locomotive and a trainload of visitors to town for a Pennsylvania Dutch supper. Old photographs show children and adults gathered around the locomotive, smiling as they pose beside the tracks. The railroad was more than transportation. It was where the community came together.

Trains remain part of the Pennsylvania landscape, carrying people and freight through towns that have grown up alongside the tracks. But the railroad also carries stories from a much earlier Pennsylvania—stories of the people who built those lines and the hardships they endured.

One of those stories begins about 30 miles west of Philadelphia, near Malvern, at a stretch of railroad known as Duffy’s Cut. A Pennsylvania historical marker near King and Sugartown Roads quietly identifies the place where 57 men died in the summer of 1832. But there was no marker then. No memorial. No cemetery. Only a railroad being built—and 57 young Irish immigrants who would never go home.

Pennsylvania was in the midst of an ambitious project called the Main Line of Public Works, a system of canals and railroads designed to connect Philadelphia with Pittsburgh. When complete, a trip that could take three or four weeks by Conestoga wagon could be made in only three or four days.

One part of that system was the Philadelphia and Columbia Railroad. At mile 59, near what is now Malvern, Irish-born contractor Philip Duffy had taken on one of the most difficult sections of the route. His crew had to cut through the densely wooded hills and ravines of Chester County and build an enormous earthen fill where a bridge might otherwise have been needed. 

Duffy needed men to do the work. In late June 1832, the sailing ship John Stamp arrived in Philadelphia carrying Irish laborers from Donegal, Tyrone, and Derry. They were young immigrants seeking the chance to build a prosperous life in America. Their average age was just 22.

But they had arrived at a dangerous moment, with Philadelphia and the Delaware Valley in the grip of a deadly cholera epidemic. To understand what happened next, it helps to understand the disease. Cholera had spread westward from its longtime home in the Ganges Delta, a vast, low-lying region of India where the Ganges and Brahmaputra rivers meet the Bay of Bengal. It traveled along trade routes and with the movement of people, eventually reaching Europe in 1831 and crossing the Atlantic the following year.

Today, we know cholera as an intestinal infection caused by the bacterium Vibrio cholerae, usually spread through contaminated food or water. But in 1832, no one knew what caused it. What people knew was what they could see: a person could be healthy in the morning and desperately sick by afternoon. Violent vomiting and diarrhea rapidly drained the body of water and salts. Severe dehydration could follow with frightening speed, and death could come within hours. There was very little doctors could do.

No one understood exactly how the disease spread. Many doctors and public officials believed illness came from poisonous vapors, or “miasmas,” rising from filth and decaying matter. Quarantines were imposed. People fled cities. Communities tried to protect themselves from anyone who might bring the disease with them.

Enter our 57 young Irish immigrants. They were part of a growing wave of Irish immigrants who joined the enormous workforce building Pennsylvania’s railroads and canals. The work was hard, dirty and dangerous, with long hours and little protection. And being Irish—particularly Irish Catholic—could make life even harder. Prejudice against the newcomers was widespread, with some Anglo-Germanic residents viewing Irish immigrants as unwholesome, dangerous, or somehow less worthy than those who had come before them.

Duffy brought 47 of the newly arrived laborers to mile 59, where they joined ten Irish workers already on his crew. They set up camp beside the railroad and went to work. But the epidemic was moving outward.

In early August, cholera reached the workers’ camp at Duffy’s Cut. Some of the workers apparently tried to flee. Evidence suggests that a quarantine may have been imposed around the camp. Whether from disease, violence, or some combination of circumstances, the men began to die. By the end of August, all 57 workers were dead.

For generations, cholera seemed to provide a straightforward explanation for their deaths. Given the epidemic raging around them, it made sense. But it left behind a troubling question. How did an entire crew of 57 young immigrants die, and why did so little remain in official records of their deaths?

According to later accounts, the first three were buried in a nearby cemetery, while the remaining workers were placed in a mass grave along the railroad’s right of way. There were no proper markers or individual graves. To date, no death certificates have been found. As the years passed, the burial site disappeared from the landscape, and the men buried there slipped from public memory.

Or almost.

In 1872, Irish-American railroad workers reportedly marked the site with a simple wooden fence. In 1909, it was replaced by a stone memorial wall built with track ballast from the old railroad line. Someone, at least, still remembered. But a fence and a wall could only do so much. For more than a century, Duffy’s Cut became little more than a forgotten stretch of railroad. Somewhere in the files of the Pennsylvania Railroad, however, the records of what had happened there were still waiting to be found.

After Penn Central went bankrupt in 1970, Joseph Tripician, longtime assistant to Pennsylvania Railroad president Martin W. Clement, removed the Duffy’s Cut file and kept it with his personal papers. Decades later, his grandson, the Rev. Dr. J. Francis Watson, discovered the file while going through his grandfather’s belongings. It even carried a warning that it was not supposed to leave the railroad office.

Francis shared what he had found with his twin brother, Dr. William Watson, a historian at Immaculata University. What began with that file soon became an investigation into what had happened to the 57 Irish workers who died at mile 59 in 1832. Together with other researchers, the brothers formed the Duffy’s Cut Project and began piecing together a story that had been largely absent from the historical record.

The investigation soon brought Duffy’s Cut back into public memory. On June 18, 2004, the site received a Pennsylvania historical marker. At the time, the accepted explanation remained that the workers had died of cholera, with anti-Irish prejudice contributing to the lack of care they received. But the marker was not the end of the investigation. It was almost the beginning.

Six weeks later, in August 2004, the Duffy’s Cut Project began archaeological excavation at the site. Finding the grave was not easy. The landscape had changed, and railroad property issues complicated the work. After more than 170 years, there was little on the surface to indicate where the workers had been buried.

Nearly five years passed. Then, on March 20, 2009, researchers Robert Frank and Patrick Barry finally found what they had been looking for: human remains. Two skulls, six teeth and roughly 80 other bones emerged from the ground.

The discovery changed everything. The story of Duffy’s Cut was no longer confined to railroad files and historical accounts. There was now physical evidence beneath the ground—evidence that could be examined.

And the bones had something to say.

Between 2009 and 2012, researchers recovered and examined the remains of seven individuals from the site. Preliminary analysis of some of the remains showed evidence of blunt-force trauma occurring around the time of death. One skull also showed an injury that researchers believed could have been caused by a bullet. The discoveries complicated the long-accepted explanation that cholera alone had caused all 57 deaths.

Researchers have proposed several explanations for what happened at the camp. Some believe the evidence points to violence against at least some of the workers, possibly connected to the fear and prejudice surrounding the cholera epidemic. Others believe some damage to the remains may have occurred after death. The evidence cannot tell us who inflicted the injuries, whether violence played a role in other deaths, or exactly what happened to the rest of the crew.

There were other clues, too. Researchers found forks, buttons, pipes, coffin nails and other remnants of the camp the men had called home. After nearly two centuries, they were no longer simply artifacts from a forgotten railroad camp. They were pieces of the lives of the people who had lived there.

In March 2012, five sets of remains—four men and one woman—were laid to rest at West Laurel Hill Cemetery in Bala Cynwyd. A memorial grave now bears 57 Irish flags, one for every worker who died at Duffy’s Cut. Then one of the men went home.

Researchers identified 18-year-old John Ruddy of County Donegal through a combination of railway records, evidence of his slight build and an unusual family clue—a congenital missing molar that relatives said ran in the family. In 2013, 181 years after his death, Ruddy was returned to Ireland and buried in Ardara.

Three years later, another victim made the journey home.

Catherine Burns was 29 years old and a widow when she left Tyrone with her father-in-law and dozens of others aboard the John Stamp. In 2015, 183 years after her death, she was returned to Tyrone, where she received a traditional Irish wake and funeral Mass before being reburied.

Catherine’s remains raised another disturbing question. Researchers examining her skull found evidence they interpreted as trauma from a sharp implement. It added yet another piece to the mystery of how the workers died, but it did not provide a complete answer.

More of the 57 workers slowly emerged from the historical record through DNA, passenger lists, railway records and other evidence. But names alone could not answer the larger questions. Clues suggest that what happened at Duffy’s Cut might not have been an isolated tragedy.

One of those clues appeared in the Village Record in November 1832. The newspaper reported that one man had fled westward from Duffy’s Cut along the unfinished railroad toward another Irish immigrant crew working near East Bradford and East Caln. The crew was working at mile 48 under another Irish contractor, Peter Connor. Historical accounts suggest it may have numbered between 100 and 120 workers—and that many of them may also have died during the cholera epidemic.

Then there was another clue. In 1909, historian Charles H. Pennypacker, a cousin of Pennsylvania Governor Samuel W. Pennypacker, wrote that Irish workers who died in Downingtown had been buried in a field—a location that is now part of Northwood Cemetery. For years, those pieces of evidence remained just that. Clues.

In 2025, researchers went looking. In April, ground-penetrating radar identified an anomaly in the area Pennypacker had described. On May 15, researchers unearthed the first human remains: a fragment of jaw, two teeth and other bone fragments.

Researchers believe the site could contain the remains of as many as 120 Irish railroad workers, although the number of people buried there has not been established. They also believe the site may be connected to Duffy’s Cut. One theory is that the man who fled Duffy’s Cut carried cholera west with him, bringing the disease to Connor’s railroad camp.

And perhaps that is what makes Duffy’s Cut so compelling. For all that we still don’t know, we know something now that generations before us did not. These were not simply names in an old railroad file. They were young people who crossed the Atlantic, found work in Pennsylvania, and spent their final days building a railroad that would outlast them by generations.

The search continues—not only to understand what happened to them, but to make sure they are remembered as more than 57 young immigrants who died beside a railroad. They came here looking for work. They left behind people who knew them, places they called home, and lives that were just beginning.

And after nearly two centuries, perhaps the simplest thing we can say is this: They were here.

The Duffy’s Cut Project did more than locate a forgotten grave. Over the years, researchers have worked to identify the people buried at Duffy’s Cut, understand how they died, and piece together the circumstances surrounding their deaths. Historians, archaeologists, forensic specialists and students have all contributed to the investigation, turning a forgotten stretch of railroad into an active site of historical research.

The work continues today, with researchers still searching for answers—and for the names of those who were lost.
